The 2013 Judges Michael Beaulac Pine Ridge Winery Napa Valley, California
If you like smooth, supple Cabernet with extraordinary depth and complexity, and exquisitely balanced Chardonnay, then you would love the fruits of Michael Beaulac's labor at Pine Ridge, where he is general manager and director of winemaking. Michael started his career in the Alexander Valley as an assistant to Chris Benz at Murphy-Goode, before skipping over the Mayacamas to make wine in the Napa Valley, first at Markham and later St. Supery before taking the reins at Pine Ridge. Amy Butler Ranchero Cellars Paso Robles, California
Amy is a specialist in the Rhone grape varieties that are so successful and popular in California's Central Coast, particularly the Paso Robles region. Amy first caught our attention as the winemaker for Edward Sellers in Paso, and she judged at our debut Winemaker Challenge in 2010. Amy now makes wine under her own brand, Ranchero Cellars.
Morgan Clendenen Cold Heaven Cellars Santa Barbara County, California Morgan has a strong commitment to well-balanced wines that exhibit structure, wines with elegance and backbone. She makes food-friendly wines with good levels of acidity, without sacrificing flavor or complexity. Morgan represents the rugged individualism of the Santa Barbara County winemaking culture.

Ken Deis Winemaking Consultant Napa Valley, California Ken is a veteran Napa Valley winemaker with a long string of exceptional vintages to his credit. That's because he spent more than a quarter-century at Flora Springs, where he made outstanding Bordeaux-style blends (Trilogy) as well as top-notch Cabernet Sauvignon, Chardonnay and Sauvignon Blanc. Ken now has his own winemaking consulting business and recently judged for us at the 2012 San Diego International Wine Competition. Gary Eberle Eberle Winery Paso Robles, California He is quite simply the Godfather of Paso Robles wine. Gary was the genius who introduced syrah to Paso while making wine at the family winery, Estrella River, in the early 1970s. Since starting his own winery more than 25 years ago he's introduced viognier and a red rhone blend, too. But it's the Paso cabernet that nearly brings a tear to the big man's eye. Gary believes passionately that cabernet sauvignon from Paso Robles is as good as any being made. Visit the winery sometime and talk him out of a bottle of one of the older Eberle Estate cabs and, we promise you, the case will be closed!
Sara Fowler Peju Province Napa Valley, California
Sara will be making her debut as a judge at Winemaker Challenge IV, and we think her appearance is long overdue! Sara was Associate Winemaker for seven years at Mt. Veeder and Franciscan, also in the Napa Valley, before joining Peju to direct the winemaking team there in 2006. She's a specialist of the first order in Bordeaux-inspired varietal wines and blends. Daryl Groom Groom Wines Barossa Valley, Australia
Daryl is a star winemaker among a galaxy of star winemakers. He was once the chief winemaker for Penfolds Grange, Australia's most sought-after and honored red wine, and now makes a line of wines under his own Groom banner. Splitting his time between Australia and California, Daryl also produces the acclaimed Colby Red, a beautiful $12 red wine that was inspired by his son Colby, with a portion of the profits going to heart research. Joe Hart Hart Winery Temecula, California
Joe has been making wine in Temecula close to 30 years now and he's a distinguished veteran of the California wine competition circuit. Joe is best known for his Syrah, but he's really a man for all seasons, so you never know what you might find in those barrels when you visit his small Temecula winery. David Hopkins Bridlewood Winery Santa Ynez Valley, California
I've seen a number of references to David as "the mad scientist" and I'm scratching my head trying to figure out why. There's nothing mad that I can detect about this 30-year veteran of winemaking along the Central Coast of California. David has a deft touch with Syrah, Chardonnay and Cabernet, and his wines are always balanced and sane. So maybe it's the hair! Vernon Kindred Fallbrook Winery Fallbrook, California Vernon is now in his fourth year Fallbrook Winery, which may well be the finest in Southern California. Fallbrook's Bordeaux blend, BDX, was voted top Bordeaux blend at the 2011 Winemaker Challenge, and its Sauvignon Blanc has been a consistent medal-winner at all of the Challenge competitions.

Craig Kritzer Frogtown Cellars Lumpkin County, Georgia
Craig is a native of Atlanta who went west into the hills of Lumpkin County, Georgia, to find a spot where he could craft world-class wines. His Bordeaux, Burgundy and Rhone-inspired wines have been consistent winners in the Challenge series of wine competitions, so it seemed only natural that we would invite this talented winemaker to join us for the Winemaker Challenge. Adam LaZarre LaZarre Wines Paso Robles, California
No California winemaker has done more in the arena of value over the past decade than Adam. He was on board when Monterey County's Hahn Estates affected a huge turnaround, making superb red and white wines in the $12 to $18 price range. Wines so good that they often took Best of Show awards at top wine competitions throughout the state, including the highest honors in Los Angeles, San Diego and Monterey. He then moved on to Villa San-Juliette in Paso Robles, where he made a dynamite merlot and a killer red Bordeaux blend, among other things. Adam is now focused on making wine under his own label. In his spare time he consults on a white wine project in Spain's Rueda district.
Susan Lueker Simi Winery Healdsburg, California
Susan is Director of Winemaking at Simi, long considered one of California's benchmark wineries. Situated in the heart of Sonoma County wine country, surrounded by the Alexander Vallley, Russian River Valley and Dry Creek Valley, Susan is expert at making top-notch Cabernet Sauvignon, Merlot, Sauvignon Blanc and Chardonnay, and she's a welcome addition to our team of judges. .jpg)
Maureen Martin Clos du Bois Winery Geyserville, California Maureen is a 20-year veteran of the Sonoma County wine industry, the first 10 years at Chateau Souverain and the past 10 at Clos du Bois, where Chardonnay and Merlot are king! This will be Maureen's second Winemaker Challenge. Jon McPherson South Coast Winery Temecula Valley, California
Jon hails from Texas but he's been making wine in the Temecula Valley of California for nearly three decades. He started at the Culbertson Winery, which later became Thornton, before moving on to South Coast, where he has enjoyed his greatest success, twice seeing South Coast named Winery of the Year at the California State Fair wine competition. John is well known for his Cabernet, Merlot and Syrah, but he also makes perhaps southern California's finest sparkling wines, too. Kim McPherson McPherson Cellars Lubbock, Texas
Kim, brother of Jon, is a legend in Texas winemaking so it's about time we rounded him up for the Winemaker Challenge. Prior to opening his own winery under the family name, Kim made wines at arguably Texas' most renowned winery, Llano Estacado.
Marcus Notaro Col Solare Columbia Valley, Washington
Marcus has been involved in winemaking in the Columbia Valley since 1995 and is currently winemaker at one of the most exciting properties in the Pacific Northwest -- Col Solare, the joint venture between Piero Antinori and Chateau Ste. Michelle. Marcus' most recent Col Solare, the 2007 vintage, earned a Platinum award at the 2011 Sommelier Challenge. Aaron Pott Pott Wines Napa Valley, California Aaron has been honored as Winemaker of the Year in the November issue of Food & Wine Magazine, a crowning accomplishment to a storied career. Aaron, a much-sought-after Napa Valley winemaking consultant, got his start under John Kongsgaard at Newton. He subsequently took the winemaking post at Chateau Troplong Mondot in Saint-Emilion, on the Right Bank of Bordeaux, and later over over to La Tour Figeac as general manager and winemaker. Pott returned to the U.S. to oversee international operations for Beringer Wine Estates and later took the winemaking reins at St. Clement. From St. Clement he moved to Quintessa, and finally, in 2007, created Pott Wines. He currently makes wines for Blackbird Vineyards, Fisher Vineyards, Stagecoach Vineyard and Seven Stones Winery, among others.

Ed Sbragia Sbragia Family Wines Healdsburg, California Big Ed was the chief winemaker at Beringer Vineyards for more than a quarter-century. While at Berginer he twice earned Wine of the Year recognition from The Wine Spectator, making him the only winemaker to have captured that honor twice.
